The showers & storms we have seen this week have been more on the scattered variety. As the next push of energy arrives... these showers will will have more organization to them. Basically, when the line passes through KY that will mean that the rain will be out of here for a couple of days.
It will return in the form of a warm front and that is why temps climb for the weekend. Highs will probably be lurking in the upper 80s by the time the weekend arrives.
The weekend forecast has been going back and forth all week. Here's what I am thinking for both Sat & Sun... isolated showers & storms can't be ruled out either day. So just be prepared for a stray shower.
